[00:00:21] Pennatula for the large one. pretty purple color! [00:00:30] Nice "polyp leaves" on which the other polyps arise. [00:01:14] can you get a zoom of the other sea pens? [00:01:18] or have you already done that? [00:02:04] we zoomed on the stumpy ones [00:02:24] ah ok. thanks! I just joined again... [00:02:48] @Steve so far only rockfish, not all larval fishes [00:03:19] its so abundant... [00:03:25] @Scott were these smaller sea pens all Kophobelemnon? [00:03:46] rockfish = redfish? common names are interchangable, right? depends on the region [00:03:58] rockfish=redfish, yes Sebastes sp. [00:04:28] LAT :-1.69683, LON : -175.39231, DEPTH : 1400.6831m, TEMP : 3.26421C, SAL : 34.59041 PSU, DO : 3.13940 mg/L [00:04:44] This looks like a Kophobelemnon type [00:05:08] Agree - kinda looks like an echiuran trace [00:05:44] zooming in again on pen [00:06:18] Sorry for being away. Nice pen forest after being in Bamboo forest earlier. [00:07:23] thanks for the zoom~~ [00:07:49] A: of course [00:09:29] LAT :-1.69687, LON : -175.39218, DEPTH : 1396.6332m, TEMP : 3.26571C, SAL : 34.58876 PSU, DO : 3.10506 mg/L [00:09:36] Halosauridae, Aldrovandia species, a deep-sea spiny eel [00:10:38] Okay, came back to that Chirostylidae on the zooanthids- looks to me like Gastrohtychus cf. iaspis originally described from Jasper Seamount 600-1189 m [00:10:54] Whereas in human males it is nostril hair that signifies [very] mature males. [00:11:03] ;-) [00:11:15] scott-horrible [00:11:23] Hear you laugh though [00:13:33] So from what I see on the quad screen we are essentially up on the top of this overall feature, right? [00:14:05] Come on Bruce! Stop pitching these softballs! [00:14:29] LAT :-1.69684, LON : -175.39208, DEPTH : 1391.5456m, TEMP : 3.27021C, SAL : 34.58829 PSU, DO : 3.09336 mg/L [00:15:12] Yes we're on the top-ish but the bathy may be 20-30m off [00:15:45] Got it. But it explains the relative flatness and these sediments.

[00:31:24] What is all that stuff at the base? [00:32:20] Hmmm.... Perhaps there were multiple colonies arising from this one spot. [00:32:24] part of the rock just given way? [00:32:33] lasers on base please? [00:32:37] We've seen in other old large colonies that new "stems" can arise... [00:32:54] thanks! [00:34:02] have seen these oph and crinoid brambles on dead coral bases throughout the dive. [00:34:31] LAT :-1.69690, LON : -175.39192, DEPTH : 1382.7581m, TEMP : 3.28940C, SAL : 34.58998 PSU, DO : 3.10443 mg/L [00:39:32] LAT :-1.69701, LON : -175.39173, DEPTH : 1379.6556m, TEMP : 3.30764C, SAL : 34.58772 PSU, DO : 2.98563 mg/L [00:39:42] Interesting that - at least while I've been watching - we've seen no primnoids today, and no Chrysogorgia (we have seen Metallogorgia and Iridogorgia). Definitely bamboo coral dominated. [00:41:34] the second seamount where we haven't seen primnoids entirely. No chrysogorgia either (really strange) its been a regular on dives [00:41:59] Synaphobranchidae, genus undetermined [00:42:39] Good call Steve! [00:43:03] Interesting axis shape. Not a nice coil. [00:44:06] Stichopathes. I wonder if the irregular shape is a reflection of long-term changes in current direction or strength? [00:44:33] LAT :-1.69708, LON : -175.39164, DEPTH : 1381.7092m, TEMP : 3.29018C, SAL : 34.58901 PSU, DO : 3.09582 mg/L [00:45:41] @Scott: maybe that is the same reason that CORI is not one plane. [00:46:00] @Asako: yes! Excellent idea. [00:49:14] Unidentified ophidiid. Couldn't see distinctive characters for an identification. [00:49:33] LAT :-1.69706, LON : -175.39170, DEPTH : 1381.5544m, TEMP : 3.33359C, SAL : 34.58600 PSU, DO : 3.04086 mg/L [00:50:03] Maybe little eddies curling around the rock edges...? [00:50:13] @Andrea - Any ideas about a genus for that ophidiid? [00:51:15] What are those lumps in the sediment in front of D2? [00:51:35] They looked like old dead stalk bases [00:53:00] randirotjan leaves the room [00:53:54] Out-freakin'-standing! [00:54:34] LAT :-1.69732, LON : -175.39160, DEPTH : 1371.8112m, TEMP : 3.36753C, SAL : 34.59707 PSU, DO : 3.03352 mg/L [00:56:02] Sorry, had a long meeting with a student. I am wondering if this tall yellow coral is an Eknomisis, or did you already suggest that @Scott? [00:56:44] I'm pretty sure this is S1, believe it or not! [00:56:59] We've seen lots of them today, although not this big. [00:57:07] We dod collect a sample earlier. [00:57:55] This one is in the box [00:57:58] We have seen Eknomisis today, but it wasn't yellow (not that i am using just color to ID) [00:58:20] I haven't actually loopked at these polyps, cause I'm making dinner. [00:58:29] Or trying, but this is pretty distracting! [00:58:41] Yeah, @Steve did say you thought it was S1, but I keep seeing branching at internode, although I also see branching just above the node..... so maybe you have it right.... [00:59:10] The earlier retracted polyps we saw were not "volcanoes" [00:59:16] But very happy you had a piece collected. [00:59:26] But this would be one of the thickest S1 skeletons I've ever seen! [00:59:34] LAT :-1.69734, LON : -175.39165, DEPTH : 1372.4618m, TEMP : 3.37275C, SAL : 34.58549 PSU, DO : 3.01514 mg/L [01:00:02] very true.... the fact that you get both kinds of branching does argue for S1, [01:00:28] so this must be the center of origin of S1 bamboos.... hahaha... [01:01:11] jillbourque leaves the room [01:01:30] You may be right! [01:02:03] janwitting leaves the room [01:02:21] Would colonization of large associate organisms cause the coral colonies to become top-heavy and topple over? [01:02:58] or would they just become too large for the current regime and topple over? [01:03:28] Current is next to nothing (slightly more on the rocky knoll) on the cap [01:03:41] We have seen asteroids feeding on these corals earlier. [01:03:51] Whoa! [01:03:55] I think both cases is likely, if there is much current... [01:03:59] Massive plexaurid? [01:04:05] wow.. [01:04:35] LAT :-1.69739, LON : -175.39167, DEPTH : 1371.3170m, TEMP : 3.34831C, SAL : 34.58539 PSU, DO : 2.99269 mg/L [01:04:39] I think this is one that we collected a few days ago. Also a massive brownish plexaurid [01:04:55] That is one sad oph... [01:05:09] one sad Ophiocreas! [01:05:12] Octocoral holiday tree [01:05:15] OPH has lost a few arms... [01:05:37] did it get kicked out of the tree? [01:05:52] haha! [01:05:59] it looks similar though depth is very different [01:06:04] An oral disc only a Mother could love. [01:06:10] this plexaurid is overrun by all kinds of things [01:06:37] I thought a few days ago you collected something more Paracis-like? [01:06:47] what was the depth before @Asako? [01:06:51] Its new for me... [01:07:08] 1370 [01:07:13] I'm pretty sure nothing like this has been collected. Could be the color morph throwing me off [01:07:25] thinking I see ophiocanthids and asteroschemids [01:07:26] I agree with you Steve~~ [01:07:41] I'm in favor of a little clipping. I think we have the time given we are on the top. [01:07:52] true true [01:07:55] I am up for this being collected...would be good to see if from the other side.... [01:07:59] Note: the last "Acanthogorgia" we collected did turn Blue in EtOH [01:07:59] possible to collect? [01:08:19] really @Steve? that's amazing [01:08:44] @Steve: we see plexaurids turn black all the time - not sure I've seen that in an acantho [01:09:14] definitely in favor of a small collection from the plexaurid [01:09:23] Inflated spines. Poisonous? Toxic?

[01:10:52] that bare bamboo looks like it came from a Dr. Seuss book.... [01:11:32] yeah, unfortunately our last open box is the hardest to reach! [01:12:15] From Allen Andrews about the large yellow coral with the thick base seen earlier - "3.2 cm diameter = 1.6 cm radius at 0.005 cm/yr (i.e. Keratoisis sp.) = ~~320 years" [01:12:24] @Steve: I don't know what you mean by that. [01:12:45] @Steve: we can't collct because we can't reach the collection box...? [01:13:19] For the pilots, its difficult to get something large to land in the box. Not a problem just might take longer [01:13:28] amandanetburn leaves the room [01:13:30] can collect then move away and then put the specimen in the box [01:14:02] Well, we don't need to collect a large piece.

[01:15:53] and the mysids! [01:16:20] what are they doing? they are always hanging around... [01:17:30] I think there are two different ophs here. [01:17:41] hard to say where to sample.. [01:18:44] pester the crinoid and maybe it will take off allowing a better shot at a top branch [01:19:18] like a Dr. Suess tree [01:19:37] LAT :-1.69728, LON : -175.39165, DEPTH : 1369.9325m, TEMP : 3.32648C, SAL : 34.59054 PSU, DO : 3.11559 mg/L [01:20:44] the current here is not strong but seems steady [01:23:25] adriennecopeland leaves the room [01:24:37] LAT :-1.69728, LON : -175.39167, DEPTH : 1369.9882m, TEMP : 3.30869C, SAL : 34.58763 PSU, DO : 3.03281 mg/L [01:26:05] perfect collection, but im not saying anything yet...

[01:27:13] sssshhhhhhhh [01:27:29] not a sample til it's...... [01:27:51] in the box [01:28:04] have to give the pilots positive reinforcement-many are in training [01:28:19] what a strange beast. will be interesting to know if all that blue comes out in the alcohol... [01:28:44] any other zooms needed on the green plexaurid before we head out [01:29:34] ssssshhhhhhh! [01:29:34] @Les: I predict it turns blue-black in ethanol.

[01:30:06] From Allen about the plexaurid just collected - "No work to date on this group for age and growth (that I know of), but apply range from other species... Diameter = 4.15 = ~~2.1 cm radius Primnoa pacifica from Alaska at 0.036 cm/yr radial = 58 years Typical "bamboo rate" of 0.005 cm/yr radial = 420 years Faster "black rate" of 0.0025 cm/yr radial = 840 years Lowest "black coral rate" of 0.0005 cm/yr = 4200 years Rate from Primnoa unlikely because of very different habitat productivity. Best guess would be between 400 and 4000 years. This species needs to be studied to know for sure. " [01:30:30] I am thinking maybe this is not a plexaurid, but an anthothelid or something with very thick axis. [01:30:52] Evan Edinger ran some dates on the Paramuricea from the Atl and Nancy Prouty has some dates on the Paramuricea biscaya from the Gulf [01:31:04] a 50 cm high P. biscaya was ~~600 yrs old [01:31:10] @Les: ooh - outside the box! Certainly the dimpled way the anthostele and anthocodium meet agrees with that idea. [01:31:15] but ages of similar sized colonies varied widely [01:31:59] "yeah, it'll go" famous last words... [01:32:09] it's in the hole!!!!

[22:10:01] You know there is an anemone researcher in our room who is currently a bit offended at the lack of a close-up [22:10:21] imaged already...unforatunately [22:10:31] I will make a note to check the anemones [22:10:43] @Tina: I did not see the rock pen.

[22:13:32] that looks like a callogorgia [22:14:08] Agree. I didn't suggest it because I didn't think it would be so deep. [22:14:31] yes, surprised at the depth! [22:14:38] wehave to collect something [22:14:48] would be a good collection [22:14:56] any seconds? [22:15:08] agree with collection of course! [22:15:23] Yes, with it's typical asteroschemids [22:15:28] Sure - collect. [22:15:42] Yes, please with an oph. [22:15:44] LAT :-0.38802, LON : -176.20132, DEPTH : 1759.8390m, TEMP : 2.61706C, SAL : 34.63651 PSU, DO : 3.11748 mg/L [22:15:50] great, I am falling asleep every time just before voting) [22:15:56] :-) [22:17:02] it can be ok 4/5 of ophiuroid? [22:17:05] interesting to see the ophs spread out, just like on the Gulf of Mexico callogorgia [22:17:10] cairns has a record of Callogorgia to 2400 m [22:17:21] is this full zoom? [22:17:23] where? [22:17:26] beautiful [22:17:52] going to set up to sample callo. very difficult location but we will try for an oph [22:17:56] well it says 37-2472 m in the Indo Pacific and N Atl. To my knowledge, its not known this deep from the N Atl [22:18:15] Callogogia's planar orientation makes it highly photogenic.... [22:18:57] As usual, I am corrected by Cairns! [22:19:04] re: depth range [22:19:06] It was referenced in Cairns and Bayer 2009 [22:19:12] Yes, oph can be minus an arm, but disc would be essential (connection to arms important too. [22:20:00] some of the OPHs on last night mystery plexaurid were DIFFICULT to take off. they had a firm grip [22:20:45] LAT :-0.38812, LON : -176.20134, DEPTH : 1759.7992m, TEMP : 2.61566C, SAL : 34.62220 PSU, DO : 3.09514 mg/L [22:24:04] brendanroark leaves the room [22:24:43] I think this may be a "cutter" and not a "snapper" [22:25:03] few hairy seconds there...

[22:39:45] I am just seeing the two asteroschema - like ophiuroids as associates [22:39:52] it may be Swiftia Steve [22:40:14] so we are going to collect-ok?

[22:41:23] Yes from me too [22:41:39] very cool wall so far [22:42:10] Doesn't take much to convince this team for a collection ;) [22:42:16] these are different ophiuroids than what we saw on Swiftia on Pao Pao. There were many skinny armed ophs. [22:42:41] Two ophs, leave one :-). There I go again...

[22:54:18] i think this is Victorgorgia [22:54:20] for me its more Victorgorgia [22:54:30] We have sampled victorgorgia already few dives ago [22:54:31] don't need to collect? [22:54:32] no collection [22:54:36] IMO [22:54:39] no [22:54:52] thx [22:54:59] ophiuroid, classic spread....
